Answer:

The total number of ways to select 5 cards from a deck of 52 cards of which 3 are aces are 4512

Explanation:

The formula to find no of ways to select is
_(n)C_(r)= (n!)/(r!(n-r)!)

There are in all 52 cards in a deck of which 4 are aces. So 48 cards are non ace cards.

Here

We have to select 5 cards of which 3 must be aces.

there are in all 4 aces.

To select three aces from four aces we get
_4C_3=4

Now we have selected three aces.

We are left to select 2 cards from the rest of the 48 cards

We get


_4_8C_2=1128

hence the total number of ways to select 5 cards from a deck of 52 cards of which 3 are aces are = 1128 (4) = 4512
